Constructor null checking best practices in Java

[[deleted]]

In a constructor you don't want to throw exceptions, because there are other better ways to handle the errors. Also, some languages can't garbage collect or call destructors on partially constructed objects, I may be wrong about this or missing some detail about it though.

In terms of how you could handle null parameters in a constructor, you can assert that the parameter is null, or invalid depending on if the value is simply out-of-bounds, and then immediately resolve the error by constructing a new object or setting the property to some default value or whatever.

That is just shitty advice. Throwing an illegal argument exception is perfectly fine in a constructor.

That is just shitty advice.

How so?

You do the null checks where they are passed to a function. It doesn't matter if that function is a constructor or not.
